Just received in the post my new Onda Vi40 dual core and i'm currently experiencing a few issues with the tablet.
It appears that the built in stereo speakers do not work correctly. I was able to play music from them using the bundled audio tracks for a short period, but am currently only able to get sound through headphones. Not sure if that would identify it as a software or hardware issue. I noticed in the audio settings menu after a reboot the volume adjustments had a white line through them as if to show they had been muted, I was unable to un-mute the speakers. I then rebooted the tablet and checked again to find that the white line had been removed, still no audio from the speakers.
The second issue I am experiencing is that once the device goes into standby/locked screen I am unable to wake the tablet. This results in the tablet needing to be rebooted. I noticed that while the tablet is off and charging the screen lock button can be pressed to show or hide the charging battery animation. And while in ICS pressing the screen lock does lock the screen, suggesting that the button isn't faulty and it is more than likely a bug in ICS. I have tried removing the screen lock option in settings and this has not resolved the issue.
Some specs then of what I currently have installed.
Android - 4.0.3
Baseband - 1.0
Kernel - 3.0.8-g783639a
Build - ICS.g12refM1005.20120612
I was unsure about changing to a custom firmware, as I wasn't sure if the dual core would cause issues running firmwares designed for the the A10 Onda tablets.
Hope this is enough information if any one is able to help.
Update: It seems that the issue with the screen not unlocking has magically resolved itself, along with an issue to do with the tablet thinking an SD card needs formatting, although I don't have one in the tablet. So the only issue now is the missing audio through the internal speakers.
